In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).延续前一部的节奏，背景同样设定在电视台，不过这次将更深入呈现幕后工作人员的办公室斗争，同时探讨什么是真，什么是假…自从余凡（陈汉玮饰）死后，周薇芸（郑惠玉饰）变得豁达，但在公事上，她将面对新对手官谢恩（黄碧仁饰）的压迫。而综艺组则交由洪韬（李南星饰）负责，他隔岸观火周官之争，从中坐收渔人之利。方彤琳（瑞恩饰）和Jason（戚玉武饰）感情稳定，在职场上缺屡受洪韬的刁难；赵菲儿成了当家阿姐，但心里却还是放不下Jason…郑氏见他兴头的模样，沉吟了一下，道：还是你一个人去吧。Whether it is file uploading, music or video players, some obvious state distinctions can be found. For example, there are several states in the file upload program: scanning, uploading, pausing, uploading successfully and uploading failed. The music player can be divided into several states: loading, playing, pausing and playing after. When clicking the same button, the behavior in upload and pause states is different, and their style class is also different.I thought this thing was the same as before, Is to rush up and bite people, So we're just shooting with guns, When the distance is close, throw it with a grenade. At the most dangerous time, even mines are thrown out, At that time, the 'round head' anti-infantry mine (still referring to Type 72 anti-infantry mine) had a 'bolt' (i.e. Safety ring) under it. Just pull it out, Throw it out like a grenade, But more powerful than a grenade, As soon as a large area is blown up, But because it is heavier, More than three grenades, Therefore, those with weak throwing ability generally dare not use it like this. Because I'm afraid I can't throw it out of the safe range and blow it up to myself, But fortunately, whatever it is, As long as you want to attack, It must be an attack on the ground, We have a great advantage from a high position. Throwing explosives from high to low can increase the throwing distance, Even if you can't throw it far away, After landing, you can also roll down a little further distance. Therefore, some comrades who throw grenades not far away can also throw mines away from a safe distance to strike the enemy. Then there is the explosive cartridge, The vast majority of people can't throw out three pieces of explosive cartridges in one go like a company commander. And it is too wasteful to throw them all like that, So he threw the explosive cartridges out one by one, When the "big grenade" is used, The reason why I dare to do this and make such "rich" moves is because there are not many others in our positions, that is, grenades, mines and explosive cartridges are plenty of explosives, and many to "tube enough", thanks to these, otherwise in the period of time without artillery support, the Vietnamese army's offensive forces increased several times, and the guns in hand alone could not hold up completely.一九四二年春天，日军发动了对我晋绥抗日根据地的疯狂“扫荡”，八路军为了集中兵力反击“扫荡”，主动撤离吕梁山区。吕梁人民的抗日斗争进入了最艰难的时期……康家寨，一个坐落于吕梁山中的村庄。八路军撤离之后，村里的形势变得动荡不安，捉摸不定。老财主康锡雪庆幸反攻倒算的时机已到，密谋夺回在减租减息斗争中失去的钱粮，妄图重树自己在村里的权势。农会干部康顺风见风使舵，甘为康锡雪出力跑腿。年轻的共产党员、农会干部雷石柱带领党员康明理和孟二愣挺身而出，决意揭穿康锡雪的阴谋……
